Running Service Probe Actions

Querying the Gateway

Tests whether the probe's configured gateway is reachable using ARP. This command runs synchronously.

run service-probe <instance_id> query gateway

Example output:

Pass: Gateway 192.168.100.10 for Service Probe with ID 1 is reachable
Fail: Gateway 192.168.200.11 for Service Probe with ID 100 is not reachable

Pinging a Host

Pings an IP address or hostname from within the probe's network context.

run service-probe <instance_id> ping <host>

Example output:

Pass: Ping to 11.100.100.1 using Service Probe with ID 1 succeeded
Fail: Ping to 11.100.100.10 using Service Probe with ID 1 failed
Not Completed: Ping to 11.100.100.99 using Service Probe with ID 99 was not completed

Querying DNS

Resolves a hostname using the probe's DNS configuration.

Version 33.5.x:

run service-probe <instance_id> query dns <fqdn>

Version 33.6.1 and later — optionally target a specific server:

run service-probe <instance_id> query dns {primary | secondary | tertiary | default} {<fqdn>}

• Omit the server keyword to query all configured servers in sequence.
• Use default to use the standard system resolver (glibc).
• Omit the FQDN to use a default test hostname.

Example output:

DNS query using Service Probe with ID 1:
Pass: DNS query for www.extremenetworks.com using primary server 11.100.100.1 succeeded
Fail: DNS query for www.extremenetworks.com using secondary server 8.8.8.8 failed

Running Shell Commands

Available in version 33.6.1 and later. Executes a shell command string inside the probe's namespace. When you run the command, you are prompted to enter the command string interactively.

run service-probe <instance_id> shell

Example output:

Command:
traceroute 11.100.100.1
Exit Status: 0
...output follows:
traceroute to 11.100.100.1 (11.100.100.1), 30 hops max, 46 byte packets
 1  192.168.1.1 (192.168.1.1)  0.547 ms  0.343 ms  0.321 ms
 2  110.110.110.2 (110.110.110.2)  0.364 ms  88.943 ms  0.375 ms
 3  11.100.100.1 (11.100.100.1)  0.287 ms  0.271 ms  0.247 ms

Running Python Scripts

Available in version 33.6.1 and later. Executes a Python script file inside the probe's namespace.

run service-probe <instance_id> python <script_file>

Example output:

Exit Status: 0

Username: admin, User ID: 1001
Group Name: admin, Group ID: 1001
